impact of emergency physician-performed ultrasound for the evaluation of patients with acute abdominal pain

Conditions: Abdominal Pain

Summary: non-traumatic abdominal pain is one of the most frequent complaints in emergency medicine. point-of-care ultrasound (pocus) has good performance in these situations. it is performed at the patient's bedside with immediate results. it has been demonstrated that a clinician-performed ultrasound was able to increase the diagnosis accuracy in patients with acute abdominal pain. however, the level of evidence of its diagnostic efficacy remains controversial in particular in europe. the principal investigators thus aimed to investigate the efficacy of early pocus on diagnostic accuracy in the context of of non-traumatic abdominal pain by a randomized control study conducted in two emergency departments (ed). secondary objectives will be comparison between the two groups for time spent in the ed before diagnosis and disposition (discharged home or hospitalization), prescription of complementary examinations and in particular, radiologic exams.

Eligibility criteria:
inclusion criteria: * patients older than 18 years * admitted for acute abdominal pain lasting for less than 5 days * availability in the ed at that time of an emergency physician trained in pocus * patient able to understand the protocol and having given oral informed consent to participate in the study or included under the emergency inclusion procedure exclusion criteria: * documented end-of-life with a do-not-resuscitate order * immediate need for management for hemodynamic stabilization * patient sent to the ed by an out-of-hospital practitioner * pregnant and breast-feeding women * no social security * under guardianship, curatorship or deprived of liberty. * do not understand french
